Abstract
The reclamation of land used for the disposal of pyritic mine waste utilizing sewage sludge as a soil conditioner has been studied in laboratory greenhouse studies and a full-scale demonstration project. Analysis of samples revealed that some of the mining waste had a pH as low as 1.8, and copper and zinc content as high as 10 mg/g, and 2 mg/g, respectively. Greenhouse column studies showed that mine waste treated with sewage sludge, agricultural limestone, and fertilizer supported a good grass growth and improved the quality of the leachate generated. Reclamation of 8 hectares of disturbed mine land began in 1976. Fair to good vegetative cover had been established on over 90 percent of the area by 1982. To assure success of the vegetation, yearly maintenance of the more toxic areas has been required. Maintenance includes addition of fertilizer and limestone, and in the worst area, irrigation during drought periods. Weeping lovegrass (Eragrostis curvula) and Fescue (Ky-31, Festuca elatior var. arundenacea) have been the most successful vegetation.
